Let's divide 63938601 by 864
Our goal is to divide 63938601 by 864.

Moving on to step 1:
864 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 864

On to step 2:
864 can be fit into 63 0 times, resulting in a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 864

Let's proceed to step 3:
If we divide 639 by 864, we get 0 and a remainder of 639.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 639, we get 639.
Take the next digit (3) from the dividend and append it to 639, then repeat: 6393 / 864

Let's proceed to step 4:
When dividing 6393 by 864, we get 7 with a remainder of 345.
The next digit of our result is 7. 
Result so far: 7.0
If we take 6048 away from 6393, we end up with 345.
Take the next digit (8) from the dividend and append it to 345, then repeat: 3458 / 864

Going ahead to step 5:
The number 864 fits into 3458 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 74.0
Subtract 3456 from 3458 to get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 864

Let's proceed to step 6:
864 goes into 26 0 times with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 740.0
Subtracting 0 from 26 leaves us with 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 864

Moving on to step 7:
864 goes into 260 0 times with a remainder of 260.
Record the quotient 0 as the next digit in the result. 
Result so far: 7400.0
If we take 0 away from 260, we end up with 260.
Append the next digit (1) from the dividend to 260 and continue with: 2601 / 864

On to step 8:
If we divide 2601 by 864, we get 3 and a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 74003.0
If we subtract 2592 from 2601, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
If we divide 90 by 864, we get 0 and a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 74003.0
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 10:
900 divided by 864 is 1 with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 74003.01
The remainder is 36 after subtracting 864 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
864 can be fit into 360 0 times, resulting in a remainder of 360.
The next digit of our result is 0. 
Result so far: 74003.01
Deduct 0 from 360 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 12:
864 goes into 3600 4 times with a remainder of 144.
The number 4 becomes the next digit in our result. 
Result so far: 74003.0104
If we subtract 3456 from 3600, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 13:
864 can be fit into 1440 1 times, resulting in a remainder of 576.
Put 1 as the next digit of the answer. 
Result so far: 74003.01041
If we take 864 away from 1440, we end up with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Let's proceed to step 14:
When dividing 5760 by 864, we get 6 with a remainder of 576.
Put 6 as the next digit of the answer. 
Result so far: 74003.010416
Subtract 5184 from 5760 to get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Step 15:
5760 divided by 864 is 6 with a remainder of 576.
The number 6 becomes the next digit in our result. 
Result so far: 74003.0104166
Subtract 5184 from 5760 to get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

The final result is 74003.0104166 with a remainder of 5.76e-06.
